got a letter from ATF stating that possesion of the semi center channel, semi lower rail and left and right rails in semi configuration but with no rivet holes drilled is legal along with one of the unfinished trunions from Dean L and that as they have previously detirmened these parts are legal to use to build a semi automatic rifle
No progress on my actual build, trying to finish the order for vz58 stuff first , and get a shotgun and a couple of other things ready to go to tech, will get back on the 60 project in a couple of weeks
